초록

This rocket motor propellant includes a combustible double-base propellant and non-carbonized, non-graphitized polymeric fibers dispersed in the double-base propellant. The double-base propellant is formed from a composition comprising nitrocellulose and at least one nitrate ester. Representative polymeric fibers include polyethylene, polypropylene, polyesters, polyamides, polyacrylonitriles and combinations thereof.
